To aZl whomit may concern: i

Be it known that we, ALBERT H. Taaensna and LOUIS I-IAssmnn, bothcitizens of the United States, and residents of the city of New York,borough of Manhattan, in the 'county and State of New York, have'invented a new'and Improved Stand Boiler and V ater Heater, of whichthe following is a full, clear, and exact description.

The present invention relates to new and useful improvements in standboilers and it pertains more particularly to a stand boiler of the typehaving a burner associated therewith for the purpose of heating watercontained in the boiler.

associated with the burner, which water heating chamber is insulatedfrom the water of lower temperature within theboiler, thus heating thewater in the water-heating chamber in a more efiicientvmanner.

It is a further object of the invention to protect that portion of thecirculating system which delivers the heated water to the boiler-"5.This wall isformed' a lent-ire 1'1, and said flange is-provided with-.aplu- 'rality of openings 12, by means of which the water from the boilerhasentra'nce tothe space. betweenjthe wall 9 and-the' bottom end wall 10of'the boiler: Leading upwardly from t-h e'wall 9'there-is aipip'e 13,

and such pipe has its upper end terminating -'at a poin't'close to thetop endiwall-ofi the boiler..5, as shown :at 14.

S." aced with respect to the wall there is a wall 15 secured to the wall9 by weldin or other suitable means at the point 16.

which is filled with asbestos or other suitable heat-insulatin material17 Projecting upwardly from this wall 15, there is a tu ular member-18,such member being of a diameter greater than the diameter of the pipe13, and this construction rovides an intervening space which is filedwith asbestos or other suitable material 19. The tubular member 18 issecured to the'upper end 14' of the circulating pipe 13, as shown at 20.n

hisconstruetion provides an intervening space .The reference character21 designates a burner whichf may be of the gas or liquid fuel type, andsaid burner is placed inrjuxta- 1 position to the bottom end wall 10 ofthe I s5 j flame will heat the water in thesipace between'the wall 9 andthe bottom en of the boiler. The water in this'space being stand boiler5 in such a manner that its wall 10 heated circulates upwardly throughthe pipe the 13 and is discharged in the upper end 0 upper end of theboiler from the action of the boiler, and is displaced by the water oflower- With the above and other objects in view,

reference is had to the accompanying drawings, in which the figure is alongitudinal sectional view of a stand boiler constructed i tween thewall 15 and the wall-9, the water Referring more particularly to thedrawin accordance with the present invention.

ings, the boiler is designated by the reference numeral 5, and iscarried by the usual stand or su port 6. Leading into the upper end ofthe oiler is a pipe 7 which su lies tion to the bottom end wall 10 o thestand temperature within the boiler 5 and which i is ,fed to the'boiler5 by means of the pipe 7. Due to the natural circulation within de--vices of thisfcharacter, the water oflowest,

temperature isat the bottom of the boiler- By providing the asbestosfilled space bewithin the heatin chamber is protected from the cooling eect of the water of lower temperature in the lower portion of the boilerand the heating operation of the water within the heating chamber isconse.

que'ntly'more' rapid than it would be were it not for the heatinsulating material. Furthermore, by providing the cheat insulating Fromthe foregoiiig it is apparent that the present invention provides a newand improved form of water-heating boilers, which, owing to itsconstruction, provides for quicker heating of the water and a protectionagainst rapid cooling of the heated water during its circulation throughthe cooled water contained within the boiler.

\Vhile in the present instance the invention is shown as a permanentpart of a stand boiler, it is obvious that the same may be made as aremovable unit and attached to stand boilers or stand boiler bottomswithout departing from the spirit of the inventioni WVhat is claimed is:

An attachment for stand boilers comprising an inverted dome-shapedmember mount-- ed upon the bottom wall of the boiler with its side wallsprovided with openings and spaced with respect to the side walls of theboiler, a circulating pipe projecting upwardly from said inverteddome-shaped member, a wall supported upon the top of said dome-shapedmember and in spaced relation thereto to provide an intervening chamber,a tubular extension projecting from said wall and surrounding saidcirculating pipe, the tubular extension being secured to the circulatingpipe at the upper end thereof, the space between the circulating pipeand the tubular extension and the wall and the inverted dome-shapedmember being filled with a heat-insulating material.
